I have pretty thick skin. I've been in the arena a long time, and that means that I am not going to get down with [Donald Trump] and go insult for insult.

We know that Donald Trump has shown a very troubling willingness to back up [Vladimir] Putin, to support Putin, whether it's saying that NATO wouldn't come to the rescue of allies if they were invaded, talking about removing sanctions from Russian officials after they were imposed by the United States and Europe together, because of Russia's aggressiveness in Crimea and Ukraine, his praise for Putin which is I think quite remarkable.

I think again we're way out of balance. We've got to rein in what has become almost an article of faith that almost anybody can have a gun anywhere at any time. And I don't believe that is in the best interest of the vast majority of people.

I've heard [Bernie] Sanders comments, and it's really caused me to wonder who's left in the progressive wing of the Democratic Party. Under his definition, [Barack] Obama is not progressive because he took donations from Wall Street; [Joe] Biden is not progressive because she supported Keystone; [Jeanne] Shaheen is not progressive because she supports the trade pact. Even the late, great Paul Wellstone would not fit this definition because he voted for DOMA.

Seen in the context of Donald Trump having committed sales tax fraud in the past, which is indisputable, I think that it's reasonable for the American public to ask, did you go beyond what's lawful, maybe scandalously lawful, but lawful, and violate the law?

Egypt has been a partner of the United States over the last 30 years, has been instrumental in keeping the peace in the Middle East between Egypt and Israel, which is a critical accomplishment that has meant so much to so many people.

I drink tons of water. Just as much water as I can possibly drink.
